Standard Peripheral Board
. .
. .
The Standard Peripheral Board (Figure 5) contains ASICs (among them four Compaq-designed
. .
ASICs) to provide connections for all system management and legacy components. This includes
. .
. .
connectors for the mouse, keyboard, IDE CD-ROM, diskette drive, video, parallel devices, SCSI
. .
devices, and Integrated Management Display (IMD). The system ROM, configuration switch,
. .
. .
and battery for CMOS are also located on this board.

Industry tolerance of server downtime continues to decrease as companies become more global,
. .
decentralized, and aware of downtime costs. A 1996 study
. .
. .
1000 companies require recovery from failure in less than three minutes. The ProLiant 7000
. .
answers the demand for high availability by incorporating the following features into the server
. .
hardware:
. .
. .
. .
Redundant network interface controller technology
. .
. .
Redundant, hot-plug fans
. .
. .
Redundant processor power modules
. .
. .
Redundant, hot-plug power supplies
. .
. .
. . Hot-plug drives
. .
. .
Compaq Smart Array 3100ES Controller
. .
. .
PCI Hot Plug technology for PCI adapters
. .
. .
Redundant components ensure that the server is highly fault-tolerant. In many cases, if a power
. .
. .
supply, fan, processor power module, or I/O board fails, the redundant standby component can
. .
take over operation with no downtime to the server. With the addition of hot-plug capabilities,
. .
. . server downtime can be eliminated while components are being replaced, added, or upgraded.
